But truth seekers claim 2016 could be the year humanity is told the truth behind one of the greatest mysteries in history.

Towards the end of last year Hillary Clinton, former First Lady and 2016 presidential candidate, said she was “going to get to the bottom” of extraterrestrials, adding: “I think we may have been visited already. We don’t know for sure.”

And just a few months before John Podesta, the chairman of Clinton’s campaign, posted an intriguing tweet.

He wrote his biggest failure of the past 12 months was “once again not securing the #disclosure of the UFO files”.

It’s statements from positions in power that have sparked a frenzy among underground investigators.

UFO disclosure activist Stephen Bassett, of the Paradigm Research Group, claims 2016 will be the year “the truth out there” finally gets revealed.

He told the Washington Post cryptic messages from Clinton and Podesta “mean something” and claims he will “make the case” for disclosure to happen in the next 12 months.

“You will see a shift in focus from the world”

He said: “I believe Clinton’s team has calculated that they cannot make it out of the election without first dealing with the ET issue.”

In an open letter to Clinton, Mr Bassett claims security documents obtained by a freedom of information request revealed billionaire businessman Laurance Rockefeller approached Bill Clinton’s administration to discuss the “potential availability of government information” about UFOs.

The letter adds Rockefeller wanted to inform Mr Clinton “there is a belief in many quarters that the government has long held classified information regarding UFOs which has not been released and that the failure to do so has brought about unnecessary suspicion and distrust”.

It adds: “Thus began a three-year effort by a notable American to convince your husband to essentially be the ‘Disclosure President’ and then end a then 46-year truth embargo on providing the full facts to the American people regarding an extraterrestrial presence engaging the human race.”

Mr Bassett’s letter continues: “Madam Secretary, it is your ambition to reach a significant milestone in American history by becoming the first President of the United States who happens to be a woman, or put another way, the 49th female head of state.

“While this would be an admirable legacy, what the American people need is less legacy and more truth. The people have lost patience with ‘in local parentis’ government that treats them like children and candidates with long lists of issues they can’t discuss because it is not convenient to their campaign or the people ‘can’t handle the truth’.”

Mr Bassett later said: “You will see a shift in focus from the world.

“More transparency, more communication among countries, an age of reform.”

It was initially dismissed as comets whizzing past – but experts now say test data proves it couldn’t be comets.
